About QuantMedia

QuantMedia is an independent quantitative research platform covering US market microstructure, algorithmic trading infrastructure, and portfolio optimization. The platform publishes open-access research papers with full Python implementations, a post-close signal dashboard scanning 500+ US equities daily, live market data across equities, forex, and commodities, and categorized financial news updated continuously from global sources.

What We Research

Research topics span VPIN order flow toxicity, Hierarchical Risk Parity portfolio construction, the Probabilistic Sharpe Ratio for backtest validation, GPU-accelerated trading infrastructure, bid-ask spread microstructure, slippage and latency modeling, genetic algorithm alpha discovery, and alternative data integration. All research is independent, non-commercial, and provided for educational purposes.

Platform Tools

The Quantum Signals dashboard applies 93 technical rules to 500+ US equities after each market close, flagging stocks above a multi-factor confluence threshold. The US equities screener tracks S&P 500 stocks, sector ETFs, and index rotation in real time. The global markets dashboard monitors major indices, forex pairs, commodities, and crypto alongside macro indicators including VIX and yield curve spreads.
